Title: Method for cooling clutch
Inventor: HIRANO SADAYUKI
IPC: F16D25/12
Filed: 1989-09-30
Abstract: PURPOSE:To maintain clutch functions well and lengthen its service life by cooling a clutch even if clutch working conditions are not met when a specific speed and/or a specific number of engine rotations is reached. CONSTITUTION:A control unit 110 for operating and controlling a pressure controlling means 44 of a non-stage transmission 2 to cool a hydraulic clutch 76 is provided. When a specific speed and/or a specific number of engine rotations is reached, the control unit 110 controls the pressure controlling means 44 to cool the clutch 76 even if clutch working conditions are not met. Thus, since the clutch 76 is cooled even if the number of engine rotations is increased by shifting to an N range or a P range during a high speed travel or by stepping on an accel pedal in the N range or P range while stopping, functions of the clutch 76 can be maintained well for lengthening the service life of the clutch 76.

Title: Method for treating melt in recovery boiler and apparatus for it
Inventor: KAA HENRIKUSON
IPC: D21C11/12
Filed: 1992-09-25
Abstract: PURPOSE: To provide a method and an apparatus for treating a melt in a recovery boiler by which amounts of sulfur compounds to enter the recovery boiler are reduced and amounts of malodorous gases emitted from a plant, amounts of sulfur emission from the recovery boiler and corrosion problems in the recovery boiler can be minimized. CONSTITUTION: The sulfur content and/or sulfur compound composition of the melt in the recovery boiler of the pulp plant is adjusted by contacting a gas with the melt. The gas may be a gaseous sulfur compound or a reducing gas. When the gas is contacted with the melt, the sodium sulfide content of the melt is increased while the sodium carbonate content is decreased so that the sulfidity of the melt increases. The sulfur-containing gas can be produced by heat-treating black liquor under pressure. As a result, the black liquor to be burned in the recovery boiler has a low sulfur content and thereby reduces the sulfur emission amounts from the boiler and the corrosion problems in the boiler.

IPC: C22C38/00
Filed: 1991-09-10
Abstract: PURPOSE:To manufacture a high silicon steel sheet having high permeability by subjecting steel sheet stock after hot rolling to annealing treatment, regulating the size of crystalline grains to specified size, subjecting it to cold rolling into a prescribed sheet thickness and thereafter diffusing Si into the steel sheet by cementation. CONSTITUTION:A high silicon steel sheet contg. 4 to 7.5% Si and <=0.008% Al is hot-rolled and is thereafter subjected to annealing treatment to form the structure of the hot rolled sheet into a coarse recrystallized one having >=0.3mm average grain size. Then, this steel is cold-rolled into a prescribed sheet thickness and is thereafter subjected to cementation of Si to diffuse Si into the steel sheet. At the time of increasing the grain size of the hot rolled sheet, the frequency of the generation of recrystallized nuclei reduces in heat treatment at the time of the cementation in the case Si is enriched, and the grain size after the cementation increases to improve its permeability.
